After its use steel with fewer stops Kc level decreased by 33% and more - 42% compared to typical for steel in the initial state. Fundamentally The method of obtaining the source images for volumetric reconstruction of surface fractures at the stage start static crack growth. A simulation of metal grain boundaries using Voronoi diagrams, providing new opportunities for analysis grain structure of metals. In solving the problem of surface reconstruction based on robust approach to the formation of static estimation of fundamental matrix followed her parameterization solved the problem of determining the parameters relative position and orientation of the camera. Were reconstructed surface of real objects, the results of which indicate preserving the aspect ratio between the size of individual elements of the surface and transferring angular relationships between these elements.
